摘要

农业和工业活动引发的全球硝酸盐污染对地下水和人类健康构成严重威胁。本研究探讨了介孔氧化铜（CuO）花作为水中硝酸盐离子去除的有效吸附剂的潜在用途。在中性pH和黑暗条件下，当NO3硝酸盐浓度为50 mg/L时，CuO花的硝酸盐吸附效率和容量分别为~ 83.5±3.39%和156 mg/g。实验数据表明，该吸附模型最符合Dubinin-Radushkevich吸附等温线和拟一级吸附动力学，表明其存在孔隙填充和物理吸附机制。研究表明，这些介孔CuO花是水处理中有效去除硝酸盐的材料。

Marigold-like mesoporous CuO flowers: An efficient adsorbent for nitrate ion removal from aqueous solutions

Global nitrate contamination, spurred by agricultural and industrial activities, poses severe risks to groundwater and human health. This study explores the potential use of mesoporous copper oxide (CuO) flowers as an efficient adsorbent for nitrate ion removal in water. The nitrate adsorption efficiency and capacity of CuO flowers were experimentally determined to be ∼83.5 ± 3.39 % and 156 mg/g for 50 mg/L of NO₃ nitrate ion concentration at neutral pH under dark conditions. The experimental data showed the best model fitting for Dubinin-Radushkevich adsorption isotherm and pseudo-first order kinetics, indicating a pore-filling and physisorption mechanism. The study shows that these mesoporous CuO flowers are promising material for effective nitrate removal in water treatment applications.

期刊介绍： Solid State Communications is an international medium for the publication of short communications and original research articles on significant developments in condensed matter science, giving scientists immediate access to important, recently completed work. The journal publishes original experimental and theoretical research on the physical and chemical properties of solids and other condensed systems and also on their preparation. The submission of manuscripts reporting research on the basic physics of materials science and devices, as well as of state-of-the-art microstructures and nanostructures, is encouraged. A coherent quantitative treatment emphasizing new physics is expected rather than a simple accumulation of experimental data. Consistent with these aims, the short communications should be kept concise and short, usually not longer than six printed pages. The number of figures and tables should also be kept to a minimum. Solid State Communications now also welcomes original research articles without length restrictions. The Fast-Track section of Solid State Communications is the venue for very rapid publication of short communications on significant developments in condensed matter science. The goal is to offer the broad condensed matter community quick and immediate access to publish recently completed papers in research areas that are rapidly evolving and in which there are developments with great potential impact.
